a combination of elements is usually used in reconnaissance geochemical exploration and distribution maps are drawn to identify probable anomalies. in this study, 102 stream sediment samples from the arid environment of mesgaran area, eastern iran, were investigated using r-mode factor analysis. a four-factor model with a cumulative variance of 75.90% clearly indicated group associations of the...

SEVERAL authors (Lyle and Foley, 1955; Naylor, Shannon, and Stanworth, 1956; Naylor and Stanworth, 1959; Guzzinati and Salvi, 1957; Pasino, Maraini, and Santori, 1963) have observed the absence of a stereoscopic perception of depth in early convergent strabismus with anomalous retinal correspondence. Even in patients with an extremely small fixed ocular deviation and harmonious anomalous retina...

In this paper, expectation and discrimination are identified as two important constructs to be considered in ecological sound design to achieve a sense of presence in virtual environments. Research to investigate the extent of this is described and the results obtained are discussed. Future avenues for research, on the basis of these results, are indicated.

When collaborating, individuals rely on situation awareness (the gathering, incorporation and utilization of environmental information) to help them combine their unique knowledge and skills and achieve their goals. When collaborating across distances, situation awareness is mediated by technology. There are few guidelines to help system analysts design systems or applications that support the ...

CSIRO and the Bureau of Meteorology advise that the information contained in this publication comprises general statements based on scientific research. The reader is advised and needs to be aware that such information may be incomplete or unable to be used in any specific situation. No relianc...

We have studied the mechanism of contour perception by recording from neurons in the visual cortex of alert rhesus monkeys. In order to assess the relationship between neural signals and perception, we compared the responses to edges and lines with the responses to patterns in which human observers perceive a contour where no line or edge is given (anomalous contour), such as the border between...

The role of soundscape design to enhance the sense of presence in virtual reality is discussed and tested. Preliminary results which compare real versus virtual soundscapes are reported.

This minitrack addresses Computer Supported Collaborative Learning Requiring Immersive Presence (CSCLIP). Immersive Presence (IP) may be characterized in at least two ways. First, it allows same-time different-place (STDP) interaction among students, instructors, equipment and Information Technology (IT). Second, it implies a “sense of presence” that is typical in lab or training environments. ...

Traditional musical instruments provide compelling metaphors for human-computer interfacing, both in terms of input (physical, gestural performance activities) and output (sound diffusion). The violin, one of the most refined and expressive of traditional instruments, combines a peculiar physical interface with a rich acoustic diffuser. We have built a new instrument that includes elements of b...
